Exploration Of The Crosslinks Between Saccadic And Vergence Eye Movement Pathways Using Motor And Visual Perturbations, Kevin Paul Schultz

All ETDs from UAB

Disconjugate movements of the two eyes can either be the result of unequal left-eye and right-eye commands or the sum of binocular conjugate and vergence commands, which symmetrically affect the two eyes in equal and opposite directions, respectively. Of particular relevance is the nature of the intra-saccadic vergence acceleration observed during combined vergence-saccade responses. This effect may be the result of asymmetric left-eye and right-eye saccades or a saccadic-driven acceleration of the vergence signal. The latter is consistent with the OPN Multiply model, in which the saccadic pause of the omnipause neurons (OPNs) elicits the vergence enhancement. We verified, in …
